Purpose

A tool-tip is a small pop-up window that labels the unlabeled control being pointed to, such as toolbar controls without caption or command buttons. Tool-tips may as well provide more descriptive text including formatting and icons. Tips are a form of progressive disclosure, eliminating the need always to have descriptive text on the screen. This time-delay mechanism makes tips very convenient, but it also reduces their discoverability. When tips are used consistently they support user’s expectation and foster predictability.

Examples

Guidelines

Use tips to label unlabeled controls and to provide additional information.
